A summing device is known that contains a register, an adder, a decoder, a pulse generator, and a group of elements AND jl. The disadvantage of such a device is its complexity and the impossibility of performing computations in binary-ae with the exact hexadecimal code. The closest in essence to this invention is a device comprising a binary-analog counter, a binary-hex-sixth counter, a pulse generator, a pulse distributor, an information input unit and a display unit, the inputs of which are connected to the binary format outputs. - hex-hex decade counter, the information inputs of which are connected to the outputs of the information input block, the output of the generator of pulses is connected to the input of the pulse distributor and the counting input of the binary-dec cal-shestide- a hexadecimal counter. In addition, this device contains a control unit and a correction unit, the input of which is connected to the output of the pulse generator, and the output to the input of the binary-decimal counter J2. The disadvantage of such a device is the limited functionality associated with the implementation of the simplest averaging algorithm. The aim of the invention is to expand the functionality of providing various laws of averaging input values and simplifying the device.} This is achieved by the fact that the proposed device contains a binary counter, an encoder, an AND-OR element, the first and second triggers, the first and second half adders, the first and the second pulse shaping, the outputs of which are respectively connected to the first and second inputs of installation 1 of the first trigger, inputs of installation O and the second trigger, counting code and input of installation About a binary counter, the outputs of which are connected to the inputs of the encoder, the single and zero outputs of the second trigger are respectively connected by -fc the first and second inputs of the first half summator, the first and second inputs / second half summator, the third and fourth inputs of which are respectively connected to the transfer outputs binary. a decimal counter and a binary-decimal-sixtieth counter, and the output of the second half-adder is connected to the installation input of the first trigger, the output of which is connected to the input of the pulse generator, the third and fourth inputs of the first half-mapper are respectively connected to the output of the pulse generator and the And element - OR, and the output of the second half-adder is connected to the counting input of the binary-decimal counter, the first inputs of the AND-OR element are connected to the outputs of the distributor pulse and the second inputs are connected to the outputs of the encoder. The proposed device makes it possible to carry out the following laws averaging none a.l-a DvOb2, the average value of two, three, and four reversion points, respectively, the binary-decimal-sixteenth code of reference at the reversion point. The drawing shows a block diagram of the proposed device, which contains a decoder 1 decimal code in a binary-decimal code, which, together with the element OR 2, form an information input unit 3, block 4 indie. The dual-hex-hexadecimal counter 5, the binary-decimal counter 6, and the second one formed 7, 8 pulses, the first and second triggers O, 1O, the first and second half summers, 11, 12, the binary counter 13, encoder 14, element 15 AND-OR, pulse distributor 16 and pulse generator 17. Input buses 18 are connected to inputs of information input unit 3, outputs of decoder 1 are connected to information inputs of a binary non-arbitrary counter 5, outputs of which are connected to inputs display unit 4, and the transfer output with inputs the accumulator 12. The output of the generator 17 pulses connected to the counting input of the counter 5, to the input of the half adder 11 and to the input of the distributor 16 pulses. The outputs of the trigger 10 are connected to the inputs of half-adders 11 and 12. The output of the first half-adder is connected to the counting input of the binary-decimal counter 6, the transfer output of which is connected to the input of the half-adder 12, the output of which is connected to the input of the trigger 9. The outputs of the formers 7, 8 are connected to the inputs the flip-flops and the inputs of the binary counter 13, the output of which is connected to the inputs of the encoder 14, together with the control buses. The outputs of the encoder 14 are connected to the first inputs of the element 15 AND-OR, the second inputs of which are connected to the outputs of the distribution of 16 bodies of pulses. The output of the element 15 AND-OR is connected to the input of the half adder 11. The transfer output of the binary; Depending on the selected operating mode, a potential is applied to one of the input terminals 19-21. The input code is entered into the device by supplying potentials to the buses 18 (for example, by pressing the appropriate keys). In this case, from the outputs of the decoder 1, the inputs of the counter 5 receive a binary-sixty-sixth bit, and the clock input of the shift is a signal from the output of the element OR 2. At the end of the clock signal, the code in the counter 5 is shifted. After entering all the bits of the input code corresponding to the first reversion point, a signal is briefly sent to the bus 22 (write). The pulse from the output of the formers 7, 8 flips both the trigger 9, Yu. The signal from the output of the trigger 9 turns on the generator, and from the output of the trigger 10 provides the passage of pulses from to

output of element 15 AND-OR through half adder 11 to input of binary counter b and passage of skew of counter 5 to trigger input 9. The pulse from the output of drivers 7, 8 records the same unit in binary counter 13. Counter 5 starts to fill with pulses from the output of the pulse generator 17, and the counter 6 - pulses from the output of element 15, AND-OR through the half-volume matrix 11. Let the control potential be applied to control bus 19 (calculation of the average from two reversion points). In this case, regardless of the signals arriving at the decoder 14 from the binary counter 13, the even outputs will have high potentials, and the rest will have low potentials. Thus, even pulses from the outputs of the distributor 16 pulses will pass to the output of the element 15 AND-OR. After the register counter 5 overflows, the transfer pulse from its output through the half-adder 12 flips trigger 9 and turns off the generator of pulses 17. As a result, in binary-decimal counter 6 there will be a number of pulses in the binary-hexadecimal code equal to half numbers that complement the dear counts3595959. Counter 5 is set to zero when the input code corresponding to the second reversal point and the secondary potential supply to bus 22 is reset, trigger 9 is again reset and pulse generator 17 is turned on. Now, after switching trigger 9 and turning off the generator in counter 6 will contain the number of pulses equal to half the number that complements the sum of the codes corresponding to the first and second reversion points. Thereafter, the potential for bus 23 (result) is applied. The pulse from the output of the formers 7, 8 throws the triggers 9, - 10. The potential from the output of the trigger 10 ensures the passage of pulses from the generator through the half adder 11 to the input of counter 6 and the transfer of the transfer of counter 6 to the input of trigger 9. After the generator 6 overflows and the generator turns off counter 5 will contain the first amount. In the mode of calculating the average of the three reversion points, the potential gives

with control bus. 20. In this case, when writing to the counter 13, a short potential is applied to the bus 22 after entering the input code into the counter 5 (the code in the counter 13 ... OO1) high potentials are set on the fourth and fourth outputs of the cipher 14, and low on the rest ; 8. In the counter 6 from the output of the element 15 AND-OR, every fourth counting pulse passes through the half-adder 11. When the potential is re-applied to the bus 22, the code 13 sets 010 on the even outputs with high potentials, the rest of the X low, and every second counting pulse passes into the counter b from the output of element 15 AND-OR. The potential is applied to the bus bar 22 for the third time in the counter 13, the code 011 is set, and at the fourth and eighth outputs of the encoder 14 - high potentials. Also, as in the first case, every fourth pulse passes to the counter G; i.e., after entering the input codes corresponding to the three reversion points, and the potential of the bus 22, counter 6 will contain the number of pulses, in addition to CX- ,. When the potential is applied to the rod 23, the device operates as in the previous case. As a result, the sum of oL-j will be contained in counter 2. In the mode of calculating the average over four points of reversion, the control potential is fed to the bus 21. In this case, when the counter is in the 13 ... 001 (first reversion point), the eighth output of the encoder 14 will have a high potential, on the rest - low, counter 010 and OH (second and third reversion points) on the sixth, seventh and eighth outputs of the encoder, high potential and when the counter is 13 .., 1OO (fourth reversal points), on the eighth output of the encoder 14, the potential is high. Otherwise, the operation of the device is similar to the previous mode; that is, after entering the codes corresponding to the four reversion points and the corresponding switching of the input terminals, counter 2 will contain the sum of ROC ,. If it is necessary to calculate the average over a larger number of reversion points, for example, eight, the first and second four points, calculate the value of the expression CX-4 -

the expression Yt, and m. e. The width of the counter 13 and the distributor of 16 pulses can also be increased, and the encoder 14 is complicated,

When the control point is fed to the bus 24, the device is brought back to its original state.

The use of the proposed device with hydrocompass allows us to simplify the measurement process and increase: to4HocTb measurement results.

The use of the proposed device with gyrotoodolites allows one to calculate the sum or difference of several angles, as well as to process the data of geodetic works. .
